That's what's up!
Just get a 25ft stainless wort chill coil (or pull the titanium coil from a free burned up chiller), some tubing, a cooler for a res, a pump, digi temp controller, and some RV antifreeze.
Then, all you need is any old second hand or even cheap/free dehumidifier/window ac, and good respect for electricity when you take them apart.. Even a small one will give you like 1/2 ton of cooling.
Bend the cold evaporator coil down into the cooler, submerging as much as possible under the antifreeze.. carefully, without kinking the copper lines. If you do crack the line, go get another free window banger or dehuey, lol.
Get a bigger hydro system? Well, then get a bigger unit to hook up to it. Get more hydro systems? Get more wort chiller coils and pumps, and use a bigger cooler for chiller res.
